Yeast stored in an airtight container can last for years. With that being said, you should note the "best by use date". Also, if you need to see if the yeast is still good, you can "bloom" your yeast by taking 1 teaspoon yeast with 1 Tbsp lukewarm water and a pinch of sugar. Let it stand 10 minutes and see if there is activity and bubbling. Then you will know it is still good. Hope this helps and Happy baking! JoAnn@KAF
